SPECIFICATION-forming part Of Letters Patent NO. 229,786, dated July 6, 1880.

I Application filed February 4, 1880.

provement in Railroad-Oars, of which the following is a specification.

My invention relates to the application to each or any of the doorways or windows in the sides of arailroad passengencar of a double 1o flexible blind or pair of blinds, which operate in a single groove in the uprights of the door or window and in double grooves or pairs of grooves in the carlings of the roof.

The object 01' the improvement is to operate a. pair ofliexible blinds in a single groove in each upright instead of a double groove, as ordinarily used, and thereby to adapt the uprights to be reduced in thickness affording more space in the-interior of the car, and lesszofening the cost of construction. I obtain this object bythe means illustrated in the accompanying drawings of which-- .Figure 1 isan elevation of an upright and carling grooved toreceive. a pair of flexible Fig. 2

represents an elevation of-the matching upright and carling and a vertical transverse section of the blinds, showing the latter as pulled down to close the opening. Fig. 3 is ai -elevation of the lower blind, showing its guide-pins. Figs. 4c and 5 represent sections atietA. and5 5, .Fig. 1, on alarger scale, showing theshape of the uprights and carlings in 1 cross-section and theirrelative proportions.

' 5. Like, letters of'reference indicate correspending parts in the several figures For the reception ofa pair of flexible blinds, K I, adapted to close, respectively, the upper and lower portions of a doorway or window- 0 opening, I provide the uprights B B at the sides of such opening with a single longitudinal groove, F, in each,-and the coincident carlings A A witha pair of similar grooves, E a D, in each, the latter being arranged one above the other, and each conformed .to the curve of 5 the carling, while both communicate at their lower ends with the single groove F in the coincident upright.

The blind K when raised occupies the grooves D, and its upper end may remain therein, as

shown in Fig. 2.

The lower blind, I, is received by the grooves E in thecarlings, being caused to enter the same by guide-pins H, projecting from the top rail of said blind I, as shown in Fig. 3, and occupy- 5 ing small guidechannels 0. These channels are formed within the grooves F and E, as shown in Figs. 1, 2, 4, and 5, and, in connection with said pins H, operate positively and satisfactorily. The same effect can be accom- ,60 plished, however, by inserting in the inortises of the lower blind a spring having a tendency to turn toward the inside of the car, so as to give said blind an inclination to turn in the direction of its own groove.

Catches Gr automatically couple 'the blinds together, so as to cause the upper blind to follow the lower when the latter is pulled down.

The blinds are preferably constructed in the manner covered by my reissued Patent No. 9,047; but such construction is not essential to the present invention.

1 claim as new and desire to protect by Letters Patentl. The combination of uprights, each provided with a single groove, and carlings, each provided with a pair of grooves opening into the single groove of the uprights, whereby two flexible car-blinds may be used in a position vertical to each other and moved into a position side by side.

2. The combination of the flexible car-blinds K I, grooves F, E, and D, guide-pins H, and channels 0, substantially as herein specified.
